I think they only produced it. If that counts then Nintendo should get Bayonetta 2 and Lego City Undercover as well.

because i didn't understand at first the criteria of this topic, "only games developed by 1st parties or co-developed" wtf is that, who asks that? what significance is in that question? who buys a console thinking "man, PS4 sure has all the great multiplats and a lot of exlcusive games, but Wii U has more games developed by Nintendo themselves so i'll get that", i subestimated the stupidity of this topic and jumped in without fully understanding it with my first comment, anyway, Bloodborne is a game co-developed by a 1st party Sony studio, and that is a big omission

I haven't found any source stating that Sony Japan DEVELOPED blood borne at all. Not mentioned on this list either http://ca.ign.com/companies/sce-studios-japan

i'm pretty sure producing a game falls under the co-developed category, i don't mind adding Bayo 2 and whatever shovelware you want to that list, the Nintendo list is nothing more than a big pile of shame, i wouldn't play any of those games, for me Nintendo doesn't even come close, just look at how Horizon looks and how Zelda looks, one looks like a modern game and the other looks like something that would've been made 10 years ago, typical Nintendo, always behind

I guess Nintendo. Sony's 3rd party exclusives always put them over Nintendo's (and M$ for that matter) overall library from Day 0 (except PS3).  From Xenogears, FFVII, Parasyte Eve, MGS, Wild Arms and FF Tactics, on PS1 to Persona 5, and Bloodborne now.

EDIT: Nevermind Sony takes it if Trico is released in Dec.  I've been waiting for Advance Wars and Metroid. Nintendo hasn't delivered, so Sony for bringing out the much needed sequel.

next time don't use IGN for research https://en.wikipedia.org/wiki/SIE_Japan_Studio#Games

Yikes...

Yikes X2..................................................................................................  I mean the Killzone games were a graphical marvel, but Guerrilla Games is unproven as a developer.  They had to clean house, hire writers and people from outside of sony.  They outsourced alot of Horizon's art too.  I have no idea if they can pull it off.

To be honest, they've all been disappointments, and I can't decide which one has disappointed me the least. I had other reasons in mind when I decided I wouldn't be getting into this generation at least quickly, but it turns out that for someone whose primary platform is PC, there haven't actually been that many interesting exclusives on consoles. The situation is finally changing a bit, but we're still not there.

I reject your definition of 1st party and apply it instead to "1st Party IPs".

With that in mind, Bloodborne. So PlayStation by default for me.
